Hi everyone, I am wondering what most folks do in the winter in the south. I live in Columbia, Sc and have always kept my pool open during the winter. It has caused me to worry on more than one winter! I usually wrap the filter and pump with insulation of some sort along with blankets and waterproof covering. Last year i used home insulation for the first time. Maybe there is a nice insulation blanket for the filter( like a horse blanket!) that i am unaware of?? it is all very ugly for sure!! I leave it on 24/7 when it is freezing. Tied to the pool at that time ! I do not have a pool cover. My pool is inground vinyl 40 x 20. 11,500 gallons two returns. I do have a new robot to clean the pool without running the skimmer!! Life saver this summer!! How does closing affect a vinyl liner? Is a cover a must in this case? Thought of closing is new to me, but it might be less winter stress, if we have a bad winter!! Anyway, what are most of you doing who live in my area?? Would love to hear your plans!!
